Thirty-one people were arrested at the Occupy site in Washington, DC during a nine-hour standoff over the weekend, after protesters refused to dismantle a wooden structure they had erected. Police also arrested several other protesters in Nashville, Tennessee and Portland, Oregon.
It was the first case of mass arrests at McPherson Square, in Washington, DC, according to the Associated Press.
Up until now, Occupy DC had enjoyed good relations with authorities, with only a few arrests linked to the protests and none in the Square.
